TITLE OF THE INVENTION
Labelling Product Using Adhesive Seal
~ACKGROUND OF THE INVENTION AND RELATED ART STATEMENT
The present invention relates to a labelling product
using adhesive seal which comprises a printed sheet of
labeIling paper, film and the like on which necessary
descriptions are printed such as labels, tags or display
cards, and a release paper coated with a release agent and
on which is bonded said sheet of labelling paper and the
like, and which is used by removing the release paper from
the labelling paper with printed description and pasting
the labelling paper on an object such as commodities.
:
As one example of prlor art labelling product using
adhesive seal, self-adhisive labels are widely known which
comprise a release paper coated with a silicone release
agent~on its surface~ and a base sheet coated with an
:: :
adhesive on the back~and whose surface forms a printed
label, the two members being pasted together. Beside the
~;; self-adhesive labels,~there are also various other
::
labelling products using adhesive seal of which the base
sheet coated with adheslve ls detachably superposed on the
surface of a release paper~coated with a release agent.
According to prior art, a sheet with printed
:::
- 1 -
2 ~ S ~
description for labelling purpose is pasted on its back
with the surface of a release paper, so that the portion
with the printed description is detached from the release
paper and pasted on a commodity, a container and the like
for use. Thus, the release paper acts solely as a support
for retaining the shape of the sheet with printed descrip-
tion until the latter is put into use.
Thus, the labelling product with adhesive seal
according to prior art includes the release paper as an
indispensable component member. However, since the
release paper is merely used as the support for retaining
the shape of the sheet with printed description until the
latter is put into use, the former is discarded as useless
once the labelling sheet is detached therefrom and pasted
on a commodity, a container and the like.
Because high grade paper such as glassine paper made
of densely arranged short fibers is often used as the
release paper to prevent excessive infiltration of
expensive silicone, it is a gross waste in terms of
effective use of resources to discard the release paper
after the printed sheet has been detached and used as a
label~
As one wav of utilizin~ the used release paper, it is
possible to collect and recycle the waste paper, as is
done with other types of paper in general. However, as
mentioned above, the release paper is coated with silicone
2~g~
on the surface and is quite dense with closely arranged
short fibers, making it difficult to dissolve the same in
the regeneration process as compared with other types of
paper. Even if it did become dissolved, short fibers are
easily washed off and yield of fiber recovery decreases.
Recovery ratio of regenerated paper is therefore low,
making the release paper unsuitable for recycling. Even
though perfectly blank as it is on the surface, the
release paper has ~herefore been collected and put to
disposal by incineration instead of being utilized as
regenerated paper.
SUMMARY OF THE INVENTION
The present invention aims at obviating the problems
encountered in the prior art labelling products as
mentioned above and providing a labelling product
comprising two support sheets with adhesive seal that are
printed with labelling descriptions and are bonded
together, so that both supports can be effectively used
without being discarded as in the case of prior art
release paper.
As a concrete means of achieving the object, the
present invention comprises two support sheets on the
surfaae and the rear surface that are bonded together.
The back of each support sheet is provided with
alternating strips of release agent and adhesive. The
- 3 -
20~8~
arrangement of alternating strips of release agent and
adhesive agent on the top and the bottom support sheets is
such that the strips of release agent on one of the
supports will come in contact with the strips of adhesive
on the other when the two support sheets are put together
into an integral form.
According to one embodiment of the present invention,
the top and the bottom support sheets are both made of a
sheet of paper that can be printed and are provided with
plural strips of release agent and adhesive on the
respective backs to be bonded with each other. The
alternating strips of release agent and adhesive are so
arranged that the strips of release agent on one of the
support sheets will come in contact with the strips of
adhesive on the other support when the two support sheets
are bonded into an integral form.
According to another embodiment of the present
invention, the top and the bottom support sheets are both
made of a sheet of paper that can be printed and are
provided with a set of plural blocks of release agent and
adhesive disposed at a predetermined interval. The blocks
are so arranged that those of release agent on one of the
support sheets will come in contact with those of adhesive
on the other when the two support sheets are put into an
integral form.
According to still another embodiment of the present
- 4 -
~ a ~ s ~
invention, the top and the bottom support sheets are both
made of a sheet of paper that can be printed, and release
agent and adhesive are alternatingly provided on the back
of each support sheet for an area that corresponds to the
area on the respective surface thereof where printing is
made. It is so arranged that the area of release agent on
one of the support sheets comes in contact with the area
of adhesive on the other when the two support sheets are
put into an integral form. Perforations are provided
along the border between the areas of release agent and of
adhesive, and label description is printed on the surface
of each support sheet at the area where said adhesive is
provided at the back.
In the labelling product according to the present
invention, the top and the bottom support sheets to be
bonded together by means of adhesive are made of a common
, : :
material such as paper that can be printed on its surface.
Alternatively, one of the support sheets may be made of
: :
paper and the other of resin film. Release agent and
adhesive are alternatingly provided at the back of both
the top and the bottom support sheets to be bonded with
each other. It is so arranged that release agent on one
of the support sheets comes in contact with adhesive on
the~other, so that the support sheets are releasably
bonded with each other while ade~uately supporting one
another. Once released, each sheet can be pasted on the
- 5
20~8~
object such as commodities by means of adhesive provided
thereon at the back. Thus, ~he labelling product with
adhesive seal can be printed with labelling descriptions
equally on the respective surface of the top and the
bottom sheets.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Preferred embodiments of labelling product with
adhesive seal according to the present invention will now
be described referring to the accompanying drawings. In
Fig. 1, the labelling product according to the present
invention when used as a label is shown in perspective.
The labelling product ln this embodiment comprises a top
sheet 1 and a bottom sheet 2, both of which being made of
paper that can be printed. On the backs of the top and
the bottom sheets 1 and 2, strips of release agent 3 and
adhesive 4 having a given width are alternatingly arranged
in parallel.
As shown in Figs. 1 and 2, said release agent 3 and
adhesive 4 to be provided on the back of the top and the
bottom sheets 1 and 2 are plural strips 3a and 4a of the
same width which is narrow as relative to the area of
respective sheets. Strips 3a of the release agent 3 and
2 ~ g 5
strips 4a of the adhesive 4 are alternatingly arranged in
parallel.
It is so arranged that strips 3a of the release agent
3 on one of the top and the bottom support sheets come in
contact with strips 4a of the adhesive 4 on the other, so
that when the two support sheets are bonded, strips 3a of
the release agent on the top sheet come in contact with
strips 4a of the adhesive 4 on the bottom sheet, and vice
versa, to form an integral mem-ber.
In case the form of the top sheet 1 and the bottom
sheet 2 are an elongated tape, perforations 5 and 6 are
respectively made at a predetermined interval along the
length thereof, and the surface of respective sheets 1 and
2 sectioned by the perforations is used as the spaces 7
and 8 for printingO The position of the perforations 5 on
the top sheet 1 corresponds to the center of the printing
space 8 on the bottom sheet 1; similarly, the position of
the perforat1ons 6 on the bottom sheet 2 corresponds to
the center of the printing space 7 on the top sheet. In
other words, the printing spaces 7 and 8 are staggered by
half the width thereof, and are arranged along the entire
length of the elongated top and the bottom sheets 1 and 2.
The printing spaces 7 and 8 thus formed are bonded
with each other at the back via the alternatingly arranged
strips of the release agen~ 3 and the adhesive 4, whereby
each acts as an adequate support for the other. Moreover,
- 8 ~
8 ~
by peeling off the printing space of either one of the
sheets from the other, the release agent 3 and the
adhesive 4 become easily separated, and the printing space
can be attached to an object suGh as a commodity by means
of the adhesive 4 provided on its back.
Although in the embodiment shown in Figs. 1 and 2,
strips 3a of the release agent 3 and strips 4a of the
adhesive 4 on the top and the bottom sheets 1 and 2 are
arranged perpendicular to the longitudinal direction of the
sheets 1 and 2, these strips can be arranged parallel to
the longitudinal direction of the sheets 1, 2. The
arrangement of the strips 3a, 4a is not limited to the
orthogonal or parallel direction, but may be diagonal
thereto.
In the embodiment shown in Fig. 3, the printing spaces
7 and 8 are formed on the top and the bottom sheets l and 2
that are made of separate pieces of paper having a given
size, unlike the first embodiment wherein the top and the
bottom sheets 1 and 2 are elongated and continuous members.
The arrangement of strips 3a and 4a of the release agent 3
and adhesive 4 on the top and the bottom sheets 1 and 2 is
the same as in the first embodiment. However, the line of
perforations 5 on the top sheet intersects that of the
perforations 6 on the bottom sheet 2. The surfaces of
respective sheets 1 and 2 sectioned by these perforations 5
and 6 are used as the spaces 7 and 8 for printing. In
g _
2 ~ 8 ~
other words, strips 3a and 4a on either one of the top and
the bottom sheets 1 or 2 are arranged perpendicular to the
direction of the strips on the other sheet.
It is noted that the release agent 3 and the adhesive
4 need not be in straight strips as in the case of the
embodiments given above, but may be plural blocks 3b of
the release agent 3 and blocks 4b of the adhesive 4 of
suitable shape and size that are alternatingly arranged at
a given interval as shown in Fig. 5. Although the blocks
3b and 4b are shown as square in Fig. 5, any other shape
or pattern such as circles and polygons may be selected.
In the embodiments shown in Figs. 1 through 4, the
release agent 3 and the adhesive 4 are provided on the
back of the top and the bottom sheets 1 and 2 in the form
of alternating and parallel strips 3a and 4a that are
disposed closely with one another. When the top and the
bottom sheets 1 and 2 are bonded together with respective
strips 3a of the release agent 3 contacting with strips 4a
of the adhesive 4, strips 4a of the adhesive 4 on the top
sheet 1 come in close contact with strips 4a of the
adhesive on the bottom sheet 2 at the edge as shown in
Figs. 2 and 4, whereby the adhesive 4 at the edge of each
strip would form threading 9 when the top and the bottom
sheets are peeled off from each other.
If the threading 9 of the adhesive 4 occurs at the
edge of strips 4a because of close contact between these
- 10 -
strips on the backs of the kop and the bottom sheets 1 and
2, the unsightly threading 9 would be exposed on the
surfaces of the top and the bottom sheets 1 and 2 when
they are peeled off from each other, deteriorating the
appearance. This bonding of adhesive strips on the top
and the bottom sheets 1 and 2 also gives rise to
resistance against the pulling force to separate the top
and the bottom sheets 1 and 3, making it difficult to
remove a label off the sheet.
As one means of overcoming the defect caused by
threading 9 of the adhesive on the top and the bottom
sheets 1 and 2 when they are to be separated, a very
narrow gap 10 is preferably provided at each border line
between the strips 3a and 4a, as shown in Fig. 7 on both
the top and the bottom sheets 1 and 2. As the gap 10 is
not coated with the adhesive 4, strips 4a of the adhesive
4 on one of the sheets 1 or 2 do not come in contact with
the strips on the other sheet at respective edge, so that
threading 9 of the adhesive 4 as mentioned above would not
occur at the border lines when the top and the bottom
sheets are pulled apart, enabling smooth peeling off
thereof.
Fig. 8 shows still another embodiment of the present
invention~ In the labelling product according to this
embodiment, the top sheet 11 and the bottom sheet 12 are
made of a base sheet of an elongated paper tape, similarly
-- 11 --
~ 5~
as in the case of the embodiment shown in Fig. 1. The
area of release agent 13 and adhesive 14 to be coated at
the backs of both the top and the bottom sheets 11 and 12
has a size comparable to the size of the printing spaces
17 and 18 on the surfaces of the top and the bottom sheets
11 and 12; for example, the ]ength of the sides of an area
is substantially the same as the length of the sides of
the printing area 17 or 18. The areas of the adhesive
agent 13 and the release agent 14 are arranged one after
the other in the longitudinal direction.
Similarly as in other embodiments, it is so arranged
that the areas of the release agent 13 on one of the top
and the bottom sheets 11, 12 come in contact with the
areas of adhesive 14 on the other. When the top and the
bottom sheets Il and 12 are bonded, the release agent 13
on the top sheet 11 comes in contact with the correspond-
ing adhesive 14 on the bottom sheet 12, and vice versa,
to form an integral member.
Perforations 15 and 16 are provided at the border
ne between areas of the release agent 13 and the
adhesive 14 along the width of the top and the bottom
sheets 11 and 12~ Among the spaces thus sectioned by the
perforations on both the top and the bottom sheets 11 and
12, spaces lla and 12a of the top and the bottom sheets
:
11 and 12 respectively which come in contact with the
: ~
- 12 -
'.
2 ~ 8 ~
adhesive 14 at the back are used as the printing areas 17
and 18 respectively.
Similarly as shown in Fig. 9, a very narrow gap 19 is
preferably provided at each border line between the areas
of the release agent 13 and the adhesive 14 on both ~he
top and the bottom sheets 11 and 12~ ~s the gap 19 is not
coated with the adhesive 14, adhesive areas on the backs
of the top and the bottom sheets 11 and 12 would not come
in contact with each other at the edge thereof, preventing
threading of the adhesive 14 when the top and the bottom
sheets are pulled apart. Although the printing spaces 17
and 18 on the top and the bottom sheets 11 and 12 are
de~ined by the perforations 15 and 16 provided along the
direction of the width of the sheets 11 and 12 in the
above embodiment, the perforations can be provided to
define frames 20, 21 at the areas of l~a and 12a which
come in contact with the adhesive 14 on the back.
According to the embodiment shown in Figs. 8 and 10,
the printing areas 17 and 18 that are coated with the
adhesive 14 at their backs are pe~led off from the
corresponding areas llb and 12b of the top and the bottom
sheets respectively where the release agent 13 is provided
to thereb~ be attached to an object such as a product.
The areas llb and 12b on the top and the bottom sheets
which correspond to the printiny spaces 17 and 18 act as
the releasing paper for the spaces 17 and 18.

In the foregoing embodiments, the top and the bottom
sheets 1 and 2, or 11 and 12 have been described as being
made of paper as the base material that can be printed on
the surface but are not limited to paper and various other
materials such as synthetic resin may be used. Both
sheets may be made of synthetic resin film; alternatively,
one surface of the sheets may be made of paper and the
other of synthetic resin film. Depending on the nature of
the product, the printed spaces need not be provided on
both sheets, but may be only on one side. The printed
space need not be fully filled with description as in the
ordinary labels, but may be provided with blank area such
as in the voucher sheet where the user can reely fill in.
According to the present invention, the labelling
product with adhesive seal comprises a top sheet and a
bottom sheet that are bonded with each other at the
respective backs where the release agent and the adhesive
are provided in such a manner that the areas of release
agent on one of the sheets come in contact with those of
~:
adhesive on the other, so that the top and the bottom
sheets can ~e printed on their surfaces for effective
utilization of the sheet material.
Unllke the prior art labelling products where one of
the sheets is exclusively used as the support for the
other, the present invention need not use pure paper made
of short fibers on which silicone is coated as the release
- 14 -
2 ~
paper. Nor is it necessary to coat th~ entire surface of
the support with silicone as the release agent.
Production cost decreases drastically according to the
present invention as it allows use of inexpensive paper
material and reduces the amount of silicone to one half.
The present invention is further advantageous in that it
makes use of the release paper as well instead of
discarding the same. Even when a portion of the support
sheet is left unused as the release paper and discarded,
as in the cases shown in Figs. 8 and 10, the quality of
the paper used is such that when the discarded support
paper is collected for recycling, it can be easily
dissolved and made into regenerated paper, greatly
contributing to effective use of resources.
Although the present invention has been described by
way o~ embodiments of labelling product, the present
invention is appIicable to various other purposes such as
display, advertisement, sign, nameplate, card and voucher
sheet~
